Designed for high-output activity in the mountains, the Solution 150 Merino Baselayer Crew builds the foundation for your skin-to-environment layering system.

Featuring innovative patented NuYarn stretch merino wool—a fabric that’s stronger, warmer, and dries faster than other merino wool fabrics by utilizing the technology of wrapping a nylon core with extra-fine merino fiber—the Solution 150 Baselayer Crew offers superior thermoregulation and moisture management and is naturally bacteria and odor resistant. The baselayer’s flatlock stitching provides seams that don’t chafe, while the crew’s shoulder panel is designed to eliminate pressure points while carrying a pack. Also, integrated thumb-holes make pulling on additional layers easy without bunch up your sleeves.
